In a User Control, I need to add a Div to the end of its parent's page. I've done this in a number of ASPX pages, where I put the code to generate the Div and its contents in the page's PreRender event handler, and it works fine. But when I try to do the same thing in the PreRender event handler for the User Control, I get the following error:
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.How do I accomplish this in a User Control?
I am working on a project in ASP.NET MVC using C# 3.0.I am using the Dundas Chart Control for OLAP. As the Dundas control does not directly support MVC it is used on a standard ASP.NET page with a codebehind file. This page is displayed in an iFrame of a normal View returned from a Controller Action.I have a button in the iFrame which submits a form via Ajax (using jQuery) to a method on the controller. I have also written an extension method for the OlapChart which returns the XML of the current report.What I am looking for is a way of getting the XML produced by the extension method to the Controller Action which handles the Ajax submit.I have only developed using ASP.NET MVC so I may be missing something obvious with Code Behind and ASP.NET controls.
View 2 RepliesI have a web application develped using VS2008 and the Dundas Charts add-on. I understand that Dundas Charts is no longer supported by Dundas and now belongs to Microsoft. I found what appear to be the chart controls and VS integration downloads:Microsoft Chart Control for Microsoft .NET Framework 3.5Microsoft Chart Controls Add-on for Microsoft Visual Studio 2008What I do not know is what happens if I install these downloads. Does my original Dundas software cease to work? Does the new MS Chart software work like the Dundas version did and is fully compatible with my existing charts? Do I need to rebuild my web sites using the MS Chart integrated software? Does the old Dundas dll file in the in folder have to be replaced or will it work as is? I have not found anything that describes how to install and use this software and the functional differences from Dundas to Microsoft ownership.
View 1 RepliesI am trying to deploy Dundas charts in .aspx to my Godaddy hosting account, but they are not showing up. The Dundas support team said I need to do the following:
If you are not using BinaryStreaming, the ASPNET user must have enough rights to write temporary images on the server's Hard drive.If using Windows 2003, the IIS_WPG user requires Write and Modify permissions.
However, of course the Godaddy support team told me I need a dedicated server to do those things. We are on a tight budget and I have to work with what I have now.
We have an application that is already deployed in the production environment. And currently it is using Dundas evaluation version. We tried updating it to the licensed version by simply pasting the dll file. but we got the error message as "The file has not been pre-compiled and cannot be requested".

View 1 RepliesI am doing account creation process which is containing 5 forms/ screens. On screens user at any screen can click previous button and go to previous screen and change data (but sure it cannot be done on 1st screen, as there is no screen prior to 1st).
If I redirect user to previous screen all data is washed. I am even clearing form. For this I will have to fetch data back from db.
Can there be a way that I may not have to get data from db and data previous form may not be cleared and user can edit anything ?
I have a report with a line chart that displays customer data. The dataset has year, month, customer, and purchases. The data category group is by year and month. The values are purchases. The series group is by customer with the data sorted in decending order by purchases and a filter of the top 10 purchasers. This works fine as intended.Now I'd like to display just one of those customers on it's own seperate chart. Since I cannot use RowNumber in the filter, how do I accomplish this (i.e. I want to show "series 1" on a chart, "series 2" on another chart, "series 3" on another chart and so on).
View 2 RepliesI have 3 columns of data that get returned from a stored procedure. Date, Error code,and Quantity. On one day we can have 8 different error codes, with different quantities.For example on the date of 18 Nov we had error code 101 = 24, error code 102 = 36, error code 103 = 4, etc. I am trying to display the different error codes in columnswith their quantity by date. There will be multiple columns for a given day because the error codes range from 101 -124. How can I display this? I currently have Just oneat a time being display based on which the end user picks.

I had a requirement to pass data between pages in my application.I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving.Following is the idea I was trying to use:
PageA.aspx:
[Code]....
In Page A Codebehind file I am creating following public properties of the inputs to access in Page B:
[Code]....
In PageB.aspx:
using previouspage directive to access page A public properties
<%@ PreviousPageType VirtualPath="~/PageA.aspx" %>
[Code]....
In Page B Codebehind file I am creating following public properties for the inputs to access in Page C:
[Code]....
in PageC.aspx:
using previouspage directive to access page A public properties
<%@ PreviousPageType VirtualPath="~/PageB.aspx" %>
[Code]....
Page C code behind file:
[Code]....
Postback is working fine from Page A to Page B, but when posting data from Page B to Page C, it is automatically redirecting to Page A.
I am not getting any kind of error or anything. page is simply redirecting to Page A. One reason as I understand is that when I post data from Page A to page B. Page A life cycle is executed and Page A becomes null.But when the data is posted to Page C. why the PreviousPage property is checked for Page A?
I want to create multi series asp.net chart in dynamically.I am new one for this concept.
View 1 RepliesI am creating a column and line chart in the same chart using reportviewer 2008.
The chart got two y series 'Number of product order' as column chart and label on left side of chart (unit number count) and total value of orders as line chart with label on right side of chart (unit $ value). Month is on x axis. I am wondering whether it can be done in reportviewer.
I'm currently developing a website that shows multiple charts that I build using data from SQL tables. I've used and followed Scott Mitchell's tutorial [URL] and K. Scott Allen's ChartBuilder class [URL] and all works well.
However when have two series that I want to show on the same Chart, if one set of data does not have all of the X values the other series does, the chart blindly puts all the data on, ignoring trying to match the X values of the other series, therefore mismatching the X values when the chart is shown.
I know that I can fiddle the data so that both sets of data have the same X values, however I'm trying to make the class handle anomalies in the data so that I don't have to worry too much about the data.

I'm going through the ASP.NET chart controls WebSamples project but I haven't found what I'm looking for yet. So basically if I had a standard bar chart with data such as below:

Mary - 32%
Anne - 88%
Displaying it in one series with names as the x axis and percentages as the y, is there anyway to change or highlight the bar colour of just one, so say all the bars in the series are blue but I want to programmatically change mary's bar colour to red. Is this possible?

I'm trying to bind a data table like:
month value
5 345
10 1300
12 450
to an ASP.NET Chart control. My problem is that the data table only contain months that have values while in the chart i want to show the full month range from 1st to the 12th.
So i used :
Chart1.ChartAreas["ChartArea1"].AxisX.Minimum = 1;
Chart1.ChartAreas["ChartArea1"].AxisX.Maximum = 12;
But when i do this, a part of the final series gets cut off in the middle like this.
I can avoid this issue by making the maximum 13 but that would not be appropriate since i just need to show the months of the year.

I have a page of several textboxes, which I would essentially like to populate from a single query. However, to begin with, I find myself unable to even populate one textbox from one query!
I have based the following on a query previously advised to me for use with drop-down lists (hence the use of DataTable). I have adapted this as follows:
AddData.aspx:
<asp:TextBox ID="tbNewDataNum" runat="server"></asp:TextBox>
AddData.aspx.vb:
Partial Public Class AddData
Inherits System.Web.UI.Page
Dim CommonFunctions As New CommonFunctions
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]....
I would like the Page_Load event to populate the textbox with this query, so that the value is present as soon as the page is presented. Also, how would you advise populating many different textboxes in one go, with one query? Is this possible too?
